"Not Synced" Indicator on Running car Tach out working

[Bmettie]

I have a not synced light on in TS on a running car(2 toothed wheel setup) where the tach in TS and the tach out on the MS3pro working fine. Should it be on? Am i actually not synced to something?

Right click on the dashboard and save dash, then reload It's an .ini thing with older TS and newer firmware. It's in the readme notes of the firmware

I just tried that and it worked for about 5 sec, then back to Not Synced. Check Engine light is also flashing code 8=Sync.

What should I look at?

The log you posted is only 14 seconds long and the engine isn't running.

Please post a longer regular datalog (Datalogging -> Start)
Start logging, then start the engine, then replicated the problem, then stop the datalog.

Doh!

[jsmcortina]

Everything looks good in that datalog. No sync loss. No CEL codes. Full RPM sync.

hmmmm that was a fresh start after i posted maybe this one from earlier. I cant see in MLV where the CEL light and no sync light is when reading a log. Do i need to upgrade to see those things?

[Bmettie]

i'm an idiot, aren't I? Thats a SD card datalog, will it have what your looking for on it?

[jsmcortina]

The SDcard datalogs won't necessarily have all the required fields.

See the manual for the field definitions.

Back to the garage...

[Bmettie]

ok heres one for real this time

[Bmettie]

Should I start messing with the noise filtering to try and solve my issue? I don't understand how I can have a sync loss with the engine continuing to run, can someone explain that to me please? I'm running a 7mgte in a supra with the original Cam Position Sensor, it uses vr pickups if it matters. To help me understand, is the sync loss a missed pulse or multiple missed pulses from the CPS? Say at higher RPM then it regains the signal and continues to run but showing a sync loss error? I'm just trying to wrap my head around it.

[jsmcortina]

There's nothing wrong during the time you datalogged, but the ECU had already been turned on for 4 minutes before you started the datalog.

Your tune says to turn on the CEL if there's more than one sync-loss ever. At some point before the datalog was started there were some sync-losses (probably during startup) as there is more than one, the CEL turns on.

I would suggest changing that number on the CEL settings page. Try 5.

James

[Bmettie]

Would those 5 have to be sequential losses in order to trigger a CEL?

[jsmcortina]

Would those 5 have to be sequential losses in order to trigger a CEL?

No, just 5 ever.

Have you done any vr sensor adjusting? Try moving the crank and the one cam sensor your using as close as possible, and move the unused can sensor away as far as possible

For a feeler guage use a dollar bill

Member JDMFreak did a write on supramania on doing an ms install

I tightened up the gaps and I can't recreate the cell, which is a good thing, but I also can't keep the not synced light out. When I reload the dash, as suggested, it'll pop right back up. What could be causing this?

[jsmcortina]

I'm not sure I'm understanding your problem. Any chance you could post a screenshot or a short video of your screen showing what's going on?

So basically when I start and run the engine I'll never come off "not synced". TS on and running prior to car ignition and engine start or TS connected after engine is already running it will always be "not synced". As suggested above and in the released notes, I should save the dashboard then reload it. But when I do save the dash and reload it the indicator will go to "synced" for about 3-5 seconds then back to "not synced". No skips/misses in the engine running, clean rev through the rev range, I'm just not understanding if its a dash issue or if i really have an issue with the engine.

This might be a good place for me post this. Do you have a custom dashboard? Meaning, mine is a custom JPEG for the background and I have changed and added gauges to the main dashboard. Mine still shows not synced even after saving and reloading, but my default TS dashboards when reloaded will show sync.
